The present invention further relates to a methodfor the permanent deformation of hair comprising providing a permanentshaping composition by mixing at least one reducing agent comprising amercapto functional group, at least one alkalizing agent and a malodorsuppressant system, applying the permanent shaping composition to thehair, allowing the permanent shaping composition to act on the hair,rinsing the hair with water, applying to the hair a fixing compositioncomprising an oxidizing agent for performing an oxidative post-treatmentof the hair, and rinsing the hair with water. The present inventionfurther relates to a use of a malodor suppressant system in acomposition for the treatment of hair, especially in a permanent shapingcomposition for the permanent deformation of hair.

BACKGROUND OF THE INVENTION

The classic technique for permanent hair shaping, i.e., permanent wavingand straightening of hair, is familiarly on two treatment steps: In thefirst step, the cystine-disulfide bridges of the keratin of the hair areopened by the action of a composition that comprises a reducingingredient (permanent shaping composition). The hair is then put intothe desires shape. In a second step, cystine-disulfide bonds are closedagain using a fixative, that is, a composition comprising an oxidizingingredient.

As classic reducing agents, compounds comprising mercapto-functionalgroups are used, for example thioglycolic acid, ammonium ormonoethanolamine salts of thioglycolic acid, 2-mercaptopropionic acid(thiolactic acid), 3-mercaptopropionic acid, cysteine, and derivativesof these compounds, cysteamine, mercaptocarboxylic acid esters, andN-alkyl-2-mercaptoacetamides.

The first step, i.e., the cystine-disulfide opening reaction, istypically carried out at a pH of 7.5 to 9 in the presence of analkalizing agent. The alkaline-adjusted permanent shaping compositionsbased on mercapto-functionalized reducing agents, however causeunpleasant odor. The unpleasant odor of the reducing agents requiresintensive perfuming of the products.

Despite the fact that commercial permanent hair deformation productshave been available for many years, still no products exist whicheffectively reduce or even completely avoid the malodor during and afterthe hair shaping process, and simultaneously provide an effectivepermanent hair shaping effect.

By using thiolactic acid, it is possible to slightly reduce the malodor.In comparison to the widely used thioglycolic acid, the permanentdeformation effectiveness of thiolactic acid is however considerablyweaker.

It is therefore a main objective of the present invention to provide acomposition and a method for permanent shaping hair which significantlyimproves the odor during and after the shaping process of the hair,provides an effective permanent hair shaping performance, and whichenhances the customer's acceptance of permanent hair shaping products.

A further objective of the present invention is to provide a permanentshaping composition and method that delivers unique elasticity andstrength of the shaped hair from the tip to the root, an improveduniformity of the shaped hair with less disordered appearance.

A further objective of the present invention is to provide a compositionand a method for permanent shaping hair which has superior hair careeffects especially with regard to improved soft feel of wet and dryhair, improved elasticity of hair and durable waving of the hair.

Another objective of the present invention is to provide a compositionand a method for permanent shaping hair which causes less hair damagethan compositions of the prior art.

A further objective of the present invention is to provide a compositionand a method for permanent shaping hair which penetrates well into thehair but less into the skin than compositions of the prior art.

Themalodor suppressant system has a distribution coefficient log P(octanol/water) of 2 or more.

Unless otherwise indicated, the following description relating to thefirst malodor suppressant defines both, the first malodor suppressant inone-component systems and in two-component systems.

In the fields of organic and medicinal chemistry, a distribution (P)coefficient is the ratio of concentrations of a compound in the twophases of a mixture of two immiscible solvents at equilibrium. Hencethese coefficients are a measure of differential solubility of thecompound between these two solvents. One of the solvents chosen is waterwhile the second is octanol. Hence the partition coefficient is ameasure of how hydrophilic (“water loving”) or hydrophobic (“waterfearing”) a chemical substance is. The partition coefficient is theratio of concentrations of un-ionized compound between the twosolutions. The logarithm of the ratio of the concentrations of theun-ionized solute in the solvents is called log P:

${\log \; P_{{oct}/{wat}}} = {{\log \left( \frac{\lbrack{solute}\rbrack_{octanol}}{\lbrack{solute}\rbrack_{water}^{{un} - {ionized}}} \right)}.}$

The log P (octanol/water) is referred hereinafter as “log P”, unlessotherwise specified.

It can be preferred that the malodor suppressants comprise at least onefunctional group selected from the group consisting of keto groups,aldehyde groups, ether groups, ester groups and hydroxyl groups. Thefirst and the second malodor suppressants can comprise or two or more ofsuch groups, either of the same type or of one or more different types.

More preferably,the second malodor suppressant has a log P (octanol/water) in the rangeof from 2 to less than 9, most preferably in the range of from 3 to lessthan 9.

While generally all types and combinations of malodor suppressantsaccording to the teaching of the present invention provide for a reducedmalodor of the compositions, it has proven to be advantageous in manycases if at least the first malodor suppressant has a log P(octanol/water) of less than 9. In a further embodiment of the inventionat least the first and the second malodor suppressant have a log P(octanol/water) of less than 9.

The first and second malodor suppressants may be a liquid at 23° C. and1013 mbar. Preferably, the malodor system (c) is a liquid at 23° C. and1013 mbar. It may also be preferred that the first and second malodorsuppressants form a solution upon mixing.

It may also be preferred that at least two malodor suppressants in acombination of first and second malodor suppressants have a log P(octanol/water) of 3 or more and a molecular weight in the range of from100 to 400 g/mol.

The density ratio mentioned above is thus measured for the malodorsuppressant system (c), and is advantageously about 1.1 or less, andshould advantageously be higher than about 0.85. Preferably, the densityratio ranges from about 1.09 to about 0.87, or from about 1.05 to about0.88, or from about 1.01 to about 0.9, or from about 1.0 to about 0.92.

The third aspect of the present invention is a method for the permanentdeformation of hair comprising the following steps:

-   -   i. providing a permanent shaping composition by mixing        -   (a) at least one reducing agent comprising a mercapto            functional group,        -   (b) at least one alkalizing agent, and        -   (c) a malodor suppressant system comprising at least a first            malodor suppressant, wherein the first malodor suppressant            has a molecular weight of from 100 to 400 g/mol, and wherein            the malodor suppressant system has a distribution            coefficient log P (octanol/water) of 2 or more;    -   ii. applying the permanent shaping composition to the hair        before or after putting the hair in a desired shape;    -   iii. allowing the permanent shaping composition to act on the        hair for a predetermined acting time sufficient for the        permanent shaping of the hair;    -   iv. rinsing the hair with water;    -   v. applying to the hair a fixing composition comprising an        oxidizing agent for performing an oxidative post-treatment of        the hair; and    -   vi. rinsing the hair with water.

In the method for the permanent deformation of hair according to thepresent invention, the carrier, the reducing agent (a), the alkalizingagent (b) and the malodor suppressant system (c) are in accordance withthe carrier, reducing agent (a), alkalizing agent (b) and malodorsuppressant system (c) described with regard to the first aspect of theinvention. In particular, the malodor suppressant system may be aone-component malodor suppressant system or a two-component malodorsuppressant system. The malodor suppressant of the one-component malodorsuppressant system is preferably selected from the group consisting ofGalaxolide, Operanide, Okoumal, habanolide and isopropylmyrstate. Themalodor suppressants of the two-component malodor suppressant system arepreferably selected from the group of compounds described above andnamed “list of malodor suppressants”. Further, the fixing composition isin accordance with the fixing composition described with regard to thesecond aspect of the invention.

The method comprises as a first step the provision of a permanentshaping composition. Said composition is provided by mixing at least onereducing agent (a), at least one alkalizing agent (b) and a malodorsuppressant system (c).

The components (a) to (c) may be mixed at any time before use. Forexample, the components (a) to (c) may be mixed before being packaged,so that the customer may purchase the permanent shaping compositionalready in mixed form. However, the components are preferably mixedimmediately before use. “Use” of the composition according to thepresent invention means working the permanent shaping composition intothe hair “Immediately before use” according to the present inventionmeans no more than 5 min before use. It is however preferred to add thehair serum no more than 3 min before use, for example, no more than 2min before use or no more than 1 min before use. It is most preferred toadd the hair serum less than 1 min before use.

The components may be mixed by any means, including using a mixing bowland/or a mixing tool, adding one component into the container of theother component followed by mixing, perforating or displacing a seallocated between the separate compartments of the components within asingle container or sachet followed by mixing.

Subsequently, after mixing the components as described above, thepermanent shaping composition is applied to the hair.

Either before or after applying the permanent shaping composition, thehair is put into the desired shape, preferably as follows: First thehair (which is washed and towel-dried) is separated into multiplesections and then these sections are rolled onto curlers. The curlersused for permanent waves have a diameter of about 5 to 13 mm, while thecurlers used for straightening must have a diameter greater than 13 mmAfter the hair is rolled on curlers, the curlers are thoroughly wetteddown using the permanent shaping composition. As an alternative, thehair may be thoroughly wetted down using the permanent shapingcomposition before being curled on the rollers, while the procedure ofrolling the hair onto curlers is the same.

The permanent shaping composition is then allowed to act on the hair fora predetermined acting time sufficient for the permanent shaping of thehair. The amount of time the permanent shaping composition stays on thehair is from about 1 to about 30 min, preferably from about 5 to about20 min. This time can be shortened by adding heat via the use of a heatradiator or a hood dryer. This time is dependent from the hair quality,the pH value, the shaping effectiveness of the color-providing shapingagent, the desired level of change as well as on the applicationtemperature.

The hair is then rinsed with water.

As a further step, the method comprises the application of a fixingcomposition comprising an oxidizing agent for performing an oxidativepost-treatment of the hair. Depending on the hair thickness and length,the amount of fixing composition, the application time and theapplication temperature can vary. Preferred application times are in therange of from 1 to 40 min, for example 2 to 20 min, more preferably 5 to10 min. Preferred application temperatures are in the range of from 25to 40° C.

After the oxidative post-treatment, the hair is rinsed with water. Thecurlers may be removed from the hair at any time after the oxidativepost-treatment, preferably before the hair is rinsed with water.

As a fourth aspect, the present invention relates to the use of amalodor suppressant system comprising a first malodor suppressant, asecond malodor suppressant, and, optionally, one or more further malodorsuppressants, wherein the first malodor suppressant is different fromthe second malodor suppressant, wherein each of the first and secondmalodor suppressants have a molecular weight of from 100 to 400 g/mol,and wherein the malodor suppressant system has a distributioncoefficient log P (octanol/water) of 2 or more, in a composition for thetreatment of hair, especially in a permanent shaping composition for thepermanent deformation of hair.

The malodor suppressant system used according to this aspect of theinvention is in accordance with the malodor suppressant system (c)described with regard to the first aspect of the invention.
